fix: Infinite recursion and Incorrect deprecation notice in PathRunnable

[georgenavarro]

Short description 📝

A recent pull request that modified LaunchAction introduced two issues into the class:

1. The setter for the pathRunnable property causes infinite recursion
2. The deprecation notice was attached to the wrong init

Solution 📦

1. I fixed the infinite recursion in the pathRunnable setter by having it modify the backing runnable property instead of having it accidentally call itself.
2. I moved the deprecation notice to the init that still accepts a PathRunnable and removed it from the init that accepts a generic Runnable.

thanks for catching this @georgenavarro - I missed this during review 🙈

this init has both runnable and pathRunnable :/

For the deprecation the following is needed:

// Consolidated init
init(
    runnable: Runnable?,
    // ....
)


@available(*, deprecated, message: "Use the init() that consolidates pathRunnable and runnable into a single parameter.")
init(
    runnable: Runnable?,
    // ....
    pathRunnable: PathRunnable?, // <-- without a default `= nil`,
    // ....
)

I agree with this, I'll prepare the change!

The installation of Swift in the Linux environment is failing. Since I checked that test and build passes locally, I'll go ahead with the merge and investigate that issue separately.
Thanks a lot @georgenavarro once again for your contributions :)
